,TUYERE SPECIFICATION lforming part of Letters Patent N o. 261,782,dated July 25, 1882.

I Application filed October 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, JACOB STOLL, of Milwaukee, in the county ofMilwaukee and State ofWisconsin, have invented a new and usefulImprovement in Tuyeres, ot' which the following is a. full, clear, andexact description.

Reference is to be had to the accompanying drawings, forming partof thisspecification, in

' which similar letters ot reference indicate corresponding parts in allthe tgures.

Figure l is a plan view of my improved tuyere. Fig. 2 is a sectionalelevation of the same, taken on the line x a: of Fig. l; and Fig. 3, anend view ofthe tuyere.

My invention consists of a removable perforated and chambered face-plateor head, and ofjacketing the pipe leading from the blower, theface-plate or head being so perforated that aportion ot' the blast willbe permitted to escape into the chamber formed by the jacket, thuspreventing all danger of gases or dust from the forge entering theblower and all danger of the tuyere becoming stopped by melted slag orinjured from heat.

A represents the pipe which leads from the blower. B represents thejacket, and C the face-plate or head. The pipe A is curved, as shown,and the end ofitis externally threaded, as shown at a, and projects ashort distance beyond the end of the jacket B, so that the face-plate orhead C may be screwed upon the to rest upon and form a good pipe A, soas joint with the end of the jacket, as shown in Fig. 2. 'Ihe face-plateor head is formed with the cham ber d, and its upper conical orroundedsurface is perforated with numerous holes, c c, and its under or datsurface is perforated with the holes e e, which lead from the chamber dback into the chamber b, formed by the jacket around the pipe A. By thisconstruction a portion ofthe blast from the pipe Ais deected from thechamber d back through the perforations e e into the chamber b, thusconducting oit' any gas or ashes which mightA enter the chamber from theforge through the chamber b, and thereby preventing its entrance to thepipe A, through which it might iind its way to the blower and interferewith its action or cause explosion. This withdrawing of the gases alsoprevents the gases from burning in the chamber or in close contact withthe end of the tuyere, thus protecting the tuyere from injury fromexcessive heat and from becoming V stopped up with slag.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In combination with the tube A and the jacket B, thehead C, formed with the chamber d, and the perforations c and e,substantially as and for the purposes set forth.
